A photographic lens of a photographic apparatus which includes a plurality of lens groups may be manufactured using a method which includes correcting a focus deviation from a designed value generated in one lens group by adjusting a distance between lenses of another lens group. The distance between lenses may be adjusted using a washer. The lenses between which the distance is adjusted may include a positive lens and a negative lens, and the lens group having the lenses between which the distance is adjusted may have a negative refractive power.

Method of manufacturing a photographic lens having multiple lens groups to correct a focus deviation, photographic lens manufactured using the method, and photographic apparatus including the photographic lens

Provided are a microfluidic chip for multiple bioassay and a method of manufacturing the same. The method includes: forming microfluidic channels by coupling a channel structure having grooves for sample channels and probe channels in a bottom surface and a substrate; forming probe immobilization regions at intersections between the probe channels and the sample channels; and forming blocking walls in the probe channels before and after each of the probe immobilization regions to prevent mixing of target sample. Since the probes are immobilized in the microfluidic channels after the formation of the microfluidic channels, difficulty in connecting fluidic channels after the immobilization of probes on a substrate can be removed. In addition, a microfluidic platform for a multiple bioassay into which a plurality of samples can be simultaneously loaded can be formed.
